Albumin is a family of globular proteins, the most common of which are the serum albumins. All of the proteins of the albumin family are water-soluble, moderately soluble in concentrated salt solutions, and experience heat denaturation. Albumins are commonly found in blood plasma and differ from other blood proteins in that they are not glycosylated. Substances containing albumins are called albuminoids.

A number of blood transport proteins are evolutionarily related in the albumin family, including serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin.^[3]^[4]^[5] This family is only found in vertebrates.^[6]

Albumins in a less strict sense can mean other proteins that coagulate under certain conditions. See § Other albumin types for lactalbumin, ovalbumin and plant "2S albumin".
